Acura RSX ECU Removal

Tools Required

  • Ratchet
  • 10mm socket
  • Phillips screwdriver

Step One

Remove the stock air box or what ever intake you have installed.


Step Two

Remove the screw (to the right of the picture) on the immobilizer.


Step Three

Remove the screw on the back of the immobilizer (hard to see in this picture). The immobilizer should pull right off at this point.


Step Four

Remove the panel underneath the glove box. There are three clips that you have to press in using a small phillips screwdriver. Take a 10mm socket and remove the three bolts holding the ECU on. There are two on each side and on on the back next to the firewall. Unplug all the connections on the ECU.
